|
|
最近才刚刚开始接触单晶（我专业是有机合成，对单晶完全外行），学习如何解析。由于基础薄，刚刚开始。目前尝试解析晶体， 如题： 我单晶chekcif文件有一些（alert或者错误），该如何修改 详见：附件chekcif反馈的文件Checkcif提示如下： Alert level C PLAT220_ALERT_2_C Large Non-Solvent C Ueq(max)/Ueq(min) ... 3.4 Ratio PLAT242_ALERT_2_C Check Low Ueq as Compared to Neighbors for C3 PLAT242_ALERT_2_C Check Low Ueq as Compared to Neighbors for C12 PLAT334_ALERT_2_C Small Average Benzene C-C Dist.
